I didn’t know this, but Adorama has run a series called 100 Tips in 100 Days. I haven’t gone through nearly all of them, but they look like good tips. Some of them seem a bit non-sensical, like Number 5, especially for D-SLR users, it doesn’t make sense that if you were in full manual mode, that you’d have to use exposure lock. On a D-SLR, manual mode means you are locked! Of course, this is different on a point and shoot. Exposure lock is probably a good thing in this situation.
In any case, enjoy the 100 Tips in 100 Days!
